Concrete Pumping Hoses With Steel Wire

Concrete pumping hoses tube is made of rubber, and reinforced steel wire in the middle layer. It can bear high pressure when concrete pouring. The concrete pumping hoses can work at extreme temperature from -50°C to 100°C.

 

2'' 2.5'' 3'' 4'' 5'' 6'' 130bar concrete pumping hoses

 

The concrete hoses tube have 3 structure layers.

  • Inner rubber: Synthetic rubber, alkali resistance, aging resistance.
  • Reinforcement: Enhancement is made of 4 wire steel layer, and withstand high burst pressure.
  • External rubber: SBR Rubber. With high wear resistance, aging resistance, heat resistance.

    Tips for choosing concrete pumping hoses.

    If the concrete particle size is less than 25mm, the inner 125mm concrete hoses can be used;
    If the concrete particle size is less than 40mm, the inner 150mm concrete hoses can be used.

     

    Concrete Pumping Hoses Feature

    • High pressure resistance
    • High wear resistance
    • Durability

     

    Application

    The concrete pumping hoses connect with drag pump for pouring, and it also use for end of hose pumping.

    Tips for concrete pumping hoses pouring

    • Before concrete pouring, check the pipe clamp first, and make sure the connector is seal.
    • When start or stop concrete pouring, the concrete pumping operator should contact with concrete hoses worker. 
    • The boom have more power strength, the end hose worker should not against the boom direction.
    • It shall be used together with vibrator to ensure the concrete pouring is dense.
    • It is best to place the clamp coupling on the concrete pumping hoses skid plate, this will avoid scratching the hose when movement.

     

    Precautions

    • When using steel rubber hose, do not allow small bend radius.
    • If the inner rubber and the flange at the outlet is obviously worn, please replace it immediately to avoid danger.
    • It is forbidden to connect the pipe tube to the end hose, because the strength of the hose is not strong enough, and the hose may be broken when concrete pouring.
